• Terre - géologie et géophysique.

  7.1 Pôles magnétiques Les pôles magnétiques de la Terre ne correspondent pas à ses pôles géographiques, c’est-à-dire aux pôles Nord et Sud. Le pôle nord magnétique se déplace suivant unetrajectoire irrégulière autour de sa position moyenne, située au large de la côte ouest des îles Bathurst, dans le nord du Canada, à plus de 1 000 km au nord-ouest de labaie d’Hudson. Le pôle sud magnétique est situé à l’opposé du pôle nord magnétique, sur le continent Antarctique, en terre Adélie. La position...

• coeur - Anatomie.

  Le développement de plaques graisseuses est en partie dû à un excès de cholestérol et de graisses animales dans l'alimentation ( voir Nutrition). Un mode de vie sédentaire peut aussi favoriser l'athérosclérose, et l'expérience montre que l'exercice physique peut la prévenir. La morphologie et la personnalité jouent également un rôle : uncaractère perfectionniste ou de battant, par exemple, appelé personnalité de type A, est fréquemment associé à un risque accru de crise cardiaque ( voir Stress...

• Plan de commentaire : La Princesse de Babylone, Voltaire

  ruinent tout sur leur passage , et n'ont pour but que de « dévaster des plaines fertiles », ce qui signifie qu'ils anéantissent tout ceque l'homme et la nature peuvent produire de beau et de bon. Et ce, de la façon la plus absurde et la plus gratuite, puisqueVoltaire rajoute avec sa sombre ironie (et un nouveau paradoxe) que le résultat est qu'ils finissent « par régner sur des cimetières». On se demande en effet quel en est l'intérêt et on ne peut que souscrire au « diagnostic » de l'auteur : c...

• Filipinas - geografía.

  programas de reforestación han tenido un éxito limitado.

No obstante, sólo el 4,9% (1997)del territorio de las Filipinas está protegido como parque y otras reservas naturales, resultando en un porcentaje muy bajo en comparación con otros países de la regió...

La partie des avirons située à l'intérieur du navire était munie d'un contrepoids e...

• navigation.

  La différence en degrés entre la direction de l'aiguille du compas (pôle Nord magnétique) et la direction du nord vrai (pôle Nord géographique) est appelée déclinaison magnétique. À l'usage des navigateurs, la déclinaison magnétique a été mesurée dans de nombreuses parties du monde. Grâce à ses mesures, des cartes ont été établies, indiquant la déclinaison magnétique approximative de n'importe quelle région. Sur ces cartes sont reliés les points d'égale déclinaison magnétique (isogones). Le gyro...

• Giraffe - biology.

  One of the most striking elements of giraffe behavior is the duel between males fighting for mating privileges. Giraffe duels are among the most extraordinary in theanimal kingdom. They start when two males approach each other and begin to rub and intertwine their necks. This behavior—known as necking—allows the opponentsto assess each other’s size and strength. Often, necking alone is enough to establish seniority. If not, the rivals begin to exchange blows with their heads. Each giraffebraces...

• Uranus (planet) - astronomy.

  V COMPOSITION AND STRUCTURE A Interior of Uranus Uranus contains mostly rock and water, with hydrogen and helium (and trace amounts of methane) in its dense atmosphere. Astronomers believe that Uranus, likeNeptune, formed from the same material—principally frozen water and rock—that composes most of the planet’s moons. As the planet grew, pressures andtemperatures in the planet’s interior increased, heating the planet’s frozen water into a hot liquid. Uranus probably has a relatively small roc...

• Greenhouse Effect.

  addition, humans cut down huge tracts of trees for lumber or to clear land for farming or building. This process, known as deforestation, can both release the carbonstored in trees and significantly reduce the number of trees available to absorb carbon dioxide. As a result of these human activities, carbon dioxide in the atmosphere is accumulating faster than Earth’s natural processes can absorb the gas. By analyzing airbubbles trapped in glacier ice that is many centuries old, scientists have d...

• Venus (planet) - astronomy.

  level winds circle the planet at 360 km/h (225 mph), making a complete rotation in only four days. These winds are said to super-rotate because they travel muchfaster than the rotation of the planet itself.

The motions of descending probes, however, have shown that the bulk of Venus’s tremendously dense atmosphere, closer to the planet’s surface, is almoststagnant. From th...

• Shark - biology.

  Sharks have two-chambered hearts that are relatively small compared to the rest of their bodies. Blood flows from the heart to the gills, where it collects oxygen fromwater and then distributes it to the other organs and tissues. The small heart produces weak blood pressure, and many sharks must swim continuously to create themuscular contractions needed to circulate blood throughout their bodies. Most sharks are cold-blooded—that is, they do not generate heat by digesting food. Instead, the bod...

• Mammal - biology.

  On land, mammals live in many different habitats, and at a wide range of altitudes. Many mammals dig burrows as refuges or as places to raise their young, but somehave developed a largely subterranean lifestyle, feeding on small animals or plant roots beneath the soil's surface. These animals, including moles and mole-rats, digthrough the ground either with spadelike front paws or with their teeth, and they detect danger by being highly sensitive to vibrations transmitted through the soil.Most m...

They learned to preserve meat by smoking it over a fire,vastly decreasing the danger of periodic starvation. Cooking also enabled them to add some for...
